I have a King combination stone. (1000 grit & 6000 grit). If you look
at the manufacturer's marks on the stone it shows the 1000 mark on the
tan part (smaller stone) and the 6000 mark on the reddish (larger
stone). I can't really figure out which side is the 1000 part and
which is the 6000 part. (I would think the finer, softer stone would
be the larger stone because it would wear away faster but that is not
the way it is marked.)
If I feel the reddish larger stone, it feels smoother so I'm guessing
it is the finer stone. When I take a bench chisel that has been
polished to a mirror finish on the back and use it on the larger
stone, I see the mirror finish degraded and scratches develop on the
back. (So I'm thinking this is really the rougher side even though it
is marked as the 6000 side.)
Then I try the other side. (the smaller tan stone) When I feel it, it
feels more coarse but I can polish out the scratches left by the
larger reddish stone. I can't quite get a mirror finish as I can with
Scary Sharp but I can get to a somewhat of a reflective finish.
On top of this, I was attending a woodworking workshop this weekend
and I asked this same question of the instructors. I got a different
answer from each of them as to which stone was coarse/fine! (No wonder
why I'm confused.)
I have a hard time believing that the stone was mismarked by the
manufacturer but the marks on the stone are in conflict with the
results I get when I use the stone.
Does anyone have the answer for this?
Thanks for your help.
BTW, I can't seem to get a mirror polish on a 6000 grit waterstone.
(Is that only possible on a 8000 grit stone?)
